I've been generating output files from PrPro CS4 for projection. Since these are in 3D, I create two separate files, one for each eye.

Source material is 1280x720p MJPEG. After editing, I output using the LEAD MJPEG Codec with just enough compression to keep file sizes to around 1.96GB each.

Recently, I was informed that the files appeared to be interlaced and the exhibitor had to use VirtualDub to deinterlace them before they could be shown as they looked terrible otherwise.

Is there some setting in the Export/AME workflow that caused this?

Or...?

I thought that I was working in a progressive format all the way.

Television is not involved in any of this - from acquisition to exhibition. No DVD's, just playing files off of servers to DLP Projectors.

I looked at the same files on my system, and see no interlace jaggies. He sent me screen grabs of the shots in VirtualDub from his system and there are.

How can I determine what's going on?

TIA,

p.s. Jeff,

received your Encore DVD book and am digesting it quite nicely. I don't usually output in that format, but have two projects that are looking for them, so I'll be digging into the Menu creation chapters this week.
